Whisper Flow Fan Filter Units and Filters

These reliable, self-powered Fan/Filter Units provide a uniform flow of microfiltered air to meet cleanliness standards down to Class 10 (ISO 4).

All models use a 3-setting (hi/med/lo), centrifugal-type fan/motor with permanently lubricated bearings mounted inside a white powder-coated steel housing with drop-in prefilter (stainless steel available).

Advanced baffling technology ensures uniform airflow across the filter face and attenuates sound. Select HEPA (High-Efficiency Particulate Air) filters, rated 99.99% efficient at removing particles ≥ 0.3 microns, or ULPA (Ultra-Low Penetration Air) filters, rated 99.999% efficient at removing particles ≥ 0.12 microns. They provide years of no-maintenance, 24/7 operation, depending on your air quality.

Housing is powder-coated CR steel.
